i915 belongs in fb-modules.  I'm not sure that sound-modules should
depend on it, as it's not a hard dependency.

Recent Intel sound and graphics hardware also needs non-free firmware
which is packaged in firmware-intel-sound and firmware-misc-nonfree
respectively.  Please check that this is included in the non-free
installation images.
